Quality Control

Our 4,4-Bis(3-Aminophenoxy)Benzophenone is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing all quality parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its light-sensitive nature and propensity for oxidation, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation of quality. Keep away from strong oxidizing agents.
